본 발명은 해상에서 움직이는 선박이나 비행체와 같은 목표물을 탐지, 추적, 식별하는 안테나 시스템에 관한 것이다.The present invention relates to an antenna system for detecting, tracking, and identifying a target such as a ship or a vehicle moving at sea.
해상 탐지용 안테나는 주로 1 ~ 8 GHz 범위의 높은 주파수 대역에 사용되는 것으로써 종래의 안테나 시스템은 탐지 및 추적 안테나의 뒷면 또는 상단에 별도로 피아식별 안테나가 여러개의 많은 안테나 소자를 이용하여 반사판에 구성되어 있어 구조적으로 단순화되지 못하였고 단일 주파수대역만 사용함으로써 반사판의 운용효율이 낮았었다.Marine detection antennas are mainly used for high frequency bands in the range of 1 to 8 GHz. Conventional antenna systems are constructed on reflectors using multiple antenna elements with separate PIA antennas on the back or top of the detection and tracking antennas. It was not structurally simplified and only a single frequency band was used, resulting in low reflector operation efficiency.
이에 본 발명은 상기의 문제점을 해소하기 위하여 탐지용 휘드혼 양옆에 대수주기 안테나를 각각 부착하여 반사판의 효율 및 피아식별 안테나의 구조를 단순화하게 하였다.Accordingly, in order to solve the above problems, the logarithmic antennas are attached to both sides of the detection horn horn to simplify the efficiency of the reflector and the structure of the PIA antenna.
본 발명의 구성을 보면 제 1 도는 본 안테나 시스템의 측면도이고, 제 2 도는 평면도이며, 제 3 도는 급전 계통도로서, 제 1 도와 같이 오프세트형 파라보릭 곡면을 변형한 반사판 전면에 극초단파 복사혼을 부착하여, 탐지용 혼 안테나(1)를 구성하고, 수직면내에 여활제곱형 복사패턴을 형성하여, 저앙각과 고앙각을 동시에 탐지할 수 있는 안테나를 구성하고, 또 탐지용 혼 안테나(1) 양옆에 UHF 또는 낮은 주파수대 극초단파 안테나(2, 2')와 전방향성 옴니 안테나(8)를 부착하여 피아식별 가능하게 구성하였다.According to the configuration of the present invention, FIG. 1 is a side view of the present antenna system, FIG. 2 is a plan view, and FIG. 3 is a power supply system diagram. The microwave radiation horn is attached to the front of the reflector on which the offset parabolic curved surface is modified as in the first diagram. Then, a detection horn antenna 1 is formed, a square square radiation pattern is formed in the vertical plane, and an antenna capable of simultaneously detecting the lower and higher elevation angles is formed, and on both sides of the detection horn antenna 1. UHF or low frequency microwave antennas (2, 2 ') and omni-directional omni antennas (8) were attached to enable PIA identification.
또한, 제 1 도와 같이 송신기, 수신기 고주파 신호(탐지용, 피아식별용)를 로타리 조인트(7)에 인입하여, 회전하면서 급전하게 하여, 탐지용 주파수대는 도파관(4)을 통하여 탐지용 혼 안테나(1)에서 복사하고, 이 복사한 전파는 다시 금속반사판(망)(3)을 통해 재반사하게 하므로, 여활제곱형 수직 복사패턴을 형성하게 하여 저앙각, 고앙각 비행체를 탐지한다.In addition, as shown in the first diagram, the transmitter and receiver high frequency signals (detection and pia identification) are introduced into the rotary joint 7 and rotated to supply power, so that the detection frequency band is detected through the waveguide 4. In 1), this radiated radio wave is reflected again through the metal reflector plate (mesh) 3, so that a vertical square radiation pattern can be formed to detect a lower angle and an elevation angle.
또 로타리 조인트(7)에 입력된 피아식별용 고주파신호(UHF)와 낮은 극초단파 주파수대는 로타리 조인트(7)를 회전통과 한 후, 동축급전선(6)을 통해 옴니안테나 결합기(11)와 피아식별용 안테나의 결합기(11)에 급전하여, 타 복사패턴이 형성되게 하여 비행체의 피아식별이 가능하게 한 안테나 장치이다.In addition, the high frequency signal (UHF) and the low microwave frequency band input to the rotary joint (7) pass through the rotary joint (7), and then through the coaxial feed line (6) for the omni antenna coupler (11) and the pia identification. It is an antenna device which feeds to the combiner 11 of an antenna, and forms other radiation patterns, and enables pia identification of an aircraft.
상기와 같이 각각의 대수주기 안테나 1개씩을 탐지용 휘드혼 옆에 부착함으로서 반사판 복사효율과 전파특성이 매우 높아지는 효과를 얻을 수 있다.As described above, by attaching each logarithmic antenna next to the detection horn, the reflector radiation efficiency and propagation characteristics can be very high.
